對于自動化工程師而言,在野外規(guī)劃工業(yè)以太網(wǎng)絡往往是件艱巨的工作。 對于公司主干網(wǎng)絡來說,網(wǎng)絡系統(tǒng)更傾向于使用諸如Cisco等商用交換機,因為它有良好的性能及密集的端口設計。在野外,工業(yè)級交換機the industrial switches are the better option due to the rugged mechanical design. 結合兩方面的考慮,兼容性是關鍵。  工業(yè)級以太網(wǎng)交換機使用專有冗余協(xié)議以確保高性能,但是專有的協(xié)議不利于兼容其它商用交換機。   芯惠通最新產(chǎn)品,JetNet 4500工業(yè)級智能網(wǎng)管型以太網(wǎng)交換機給您一個完美的答案。JetNet 4500系列工業(yè)級智能網(wǎng)管型以太網(wǎng)交換機支持RSTP over Super Ring 技術。RSTP over Super Ring 技術為高級冗余網(wǎng)絡提供解決方案,可以將使用不同冗余協(xié)議(i.e. IEEE 802.1w Rapid Spanning Tree Protocol 快速生成樹協(xié)議及Super Ring自愈環(huán)協(xié)議)的交換機聯(lián)起來,并可擴大了冗余網(wǎng)絡的覆蓋面。RSTP over Super Ring 技術將使用Super Ring協(xié)議工業(yè)級交換機的兩個端口與,使用RSTP協(xié)議的商用交換機的兩個端口連接起來以實現(xiàn)冗余?! n active link where data is transmitted is connected with one port in the switch. The other port connected with another switch is a hot standby link. Constantly monitoring the hot standby link and will switch over in seconds once the active link is disconnected or breaks. The process of switching the backup route from one switch to another is transparent to the user.
